Fig. 4: Polymer length has a limited effect on condensate architecture in comparison to pairwise interaction strengths.
From: Differential interactions determine anisotropies at interfaces of RNA-based biomolecular condensates
The interaction between beads of polymers A and B was set to a |εB-A | = –4, or b |εB-A | = –4.5. The volume fractions for the three polymers are shown as a function of the distance from the center of the condensate (similar to Fig. 3d). We observe that molecule length affects partitioning into dilute or dense phase. Notably, varying length does not cause polymer C to a adsorb when it previously did not, or b stop adsorbing when it previously did. The interaction strength between the monomers has a much more extensive effect on condensate architecture and interface organization than the length of the polymer. If a given datapoint had an error greater than 0.1, then that datapoint was omitted. Error bars indicate the standard errors about the mean across three replicates. Source data are provided—see “Data availability” statement.
